CASTROL BIOSTAT

Environmentally acceptable stern tube and gear oil**, with outstanding performance when compared with mineral oils

WHAT IT’S FOR

  • Designed to protect stern tube bearings, thruster gear boxes, reduction gear, spur, helical and planetary gear units, couplings, rolling and sliding bearings, deck machinery gearboxes
Castrol Biostat

WHY YOU NEED IT

  •  To comply with the US Vessel General Permit (VGP)
  •  Castrol BioStat products are committed to certified carbon neutral*** in accordance with PAS 2060 from 2021
Path 360
*In accordance with PAS 2060, see www.castrol.com/cneutral for more information.
***The CO2 emissions are calculated in accordance with the Greenhouse Gas Protocol’s Product Life Cycle Standard and include life cycle
emissions. The demonstration of carbon neutrality is assured by an Independent Third-Party and certified to BSI’s PAS 2060 carbon neutral specification. See www.castrol.com/cneutral for more information.
 
  • Approved by major original equipment manufacturers
  • To preserve the efficiency of stern tubes and thrusters and help to reduce maintenance: the oil combines excellent protection, extended drain performance and versatility

 

ENVIRONMENTALLY ACCEPTABLE LUBRICANT (EAL)**     

  • Meets the definition of an EAL** under the 2018 US Vessel Incidental Discharges Act (VIDA) based on the requirements in the 2013 US VGP
  • OSPAR**** tested and registered
  • Reduced environmental impact***** when compared to conventional mineral oils

    o   Superior marine biodegradation

    o  Significantly reduced bioaccumulation****** and toxicity to marine organisms

    o  Enhanced renewability

 

**A lubricant, including any oil or grease, that is ‘‘biodegradable,’’ ‘‘minimally toxic,’’ and ‘‘not bio accumulative’’ as defined by US VGP 2013.
****OSPAR – Oslo and Paris Convention for the Protection of the Marine Environment of the North-East Atlantic.
